An important tribe of Salishan stock formerly found along Spokane River in Washington and adjacent parts of Idaho. They were first noted by Lewis and Clark in 1804. About 1841 they came under the influence of the Jesuits. The Washington tribes were gathered upon the Colville reservation in 1872. The Idaho tribes are associated with the Coeur d'Alene, and are all Catholics, while at Colville the Lower Band is Protestant. They closely resemble the Coeur d' Alene and the Kalispel.
